Abstract
BACKGROUND Matrix metalloproteases (MMPs), enzymes with the ability to degrade the extracellular matrix, play an important role in tissue invasion by cutaneous malignant melanoma (CMM). One specific MMP, collagenase-3 (MMP-13), is thought to have a key function in the activation of MMP. AIMS To evaluate the expression of MMP-13 in CMM and assess its possible relationship to clinical and pathological parameters. METHODS MMP-13 expression was analyzed in 51 paraffin-embedded tumor samples from patients with invasive CMM, ten samples from in situ melanomas, and in eight samples from benign lesions (three dermal melanocytic nevi, three compound melanocytic nevi and two atypical melanocytic nevi) using immunohistochemical techniques. The median follow-up period in patients with invasive CMM was 50 months. RESULTS Benign lesions were consistently negative for MMP-13, whereas three of the ten in situ melanomas (30%) and 23 of the 51 invasive CMMs (45%) showed positive immunostaining for MMP-13. The percentage of MMP-13-positive tumors correlated significantly and positively with the mitotic index (p=0.002) in invasive CMM. However, our results did not show any significant association between tumoral MMP-13 expression and relapse-free survival in patients with invasive CMM. CONCLUSIONS MMP-13 appears to be a factor associated with tumor aggressiveness in CMM. It seems to eliminate an important barrier not only against tumoral invasion but also against proliferation.

Abstract
Epidermal growth factor receptor (EGFR) is a membrane receptor expressed in a variety of solid human cancers and directly related with poor prognosis. The objective of this work was to evaluate the EGFR content in breast carcinomas, its possible relationship with different clinical-pathological parameters, and its potential prognostic significance and predictive value. EGFR levels were examined by radioligand binding assays in 846 patients with invasive breast cancer. The median follow-up period was 50 months. There was a wide variability of EGFR levels among the studied tumors (0.01-403 fmol/mg protein). Statistical analysis showed that EGFR levels were significantly higher in younger patients (p=0.0001). EGFR were also notably higher in ER-negative or PgR-negative tumors than in ER-positive (p=0.0001) or PgR-positive tumors (p=0.001). In addition, the presence of high intratumoral EGFR levels (cut-off: 6 fmol/mg protein) was associated with both shorter relapse-free survival (p=0.04) and overall survival (p=0.01) in the group of patients as a whole, as well as with overall survival in the subgroup of patients without any type of systemic adjuvant treatment (p=0.02). However, EGFR levels did not achieve significance as independent prognostic factor in the multivariate analysis. There is a wide variability of intratumoral EGFR levels in breast carcinomas, and these protein levels correlated positively with a poor prognosis in the t univariate analysis. However, further studies are necessary in order to assess the possible clinical value of EGFR in combination with other essential components of the EGFR family network.

Abstract
Background The protein encoded by the c-erbB-2 gene is a membrane receptor expressed in a variety of solid human cancers and directly related to poor prognosis. The objective of this work was to evaluate the clinical value of the quantification of membranous oncoprotein levels in gastric cancer. Materials and methods Membranous c-erbB-2 levels were examined by means of a sandwich immunoenzymatic assay in 82 patients with gastric cancer. The median follow-up period for these patients was 16 months. In addition, c-erbB-2 expression was analyzed by immunohistochemistry in 57 gastric carcinomas. Results Membranous c-erbB-2 levels ranged widely in the studied tumors (44–112,000 NHU/mg protein). Median c-erbB-2 content was significantly higher in intestinal-type tumors than in diffuse-type tumors (p=0.01). In addition, high levels of c-erbB-2 were significantly associated with shorter relapse-free survival and overall survival in patients with resectable gastric carcinomas (p=0.01 and p=0.04, respectively). However, the correlation between immunohistochemistry and ELISA determinations did not reach statistical significance. Conclusion Our results suggest a potential prognostic value of membranous c-erbB-2 quantification by immunoenzymatic assay in gastric cancer. However, its possible role in the selection of patients with a view to the possible introduction of Herceptin as a novel drug against gastric cancer is at present uncertain.

Abstract
BACKGROUND Hyaluronan a high-molecular weight glycosaminoglycan, is considered to be involved in the growth and progression of malignant tumours. The objective of this work was to evaluate the cytosolic hyaluronan content in gastric cancer cells, its possible relationship with clinicopathological tumour parameters and its potential prognostic significance. METHODS Cytosolic hyaluronan levels were examined utilizing immunoenzymatic techniques in 129 patients with gastric cancer. The mean follow-up period for these patients was 28 months. RESULTS Cytosolic hyaluronan levels ranged widely in tumours as well as in adjacent mucosal samples (median (range) 2822 (50-24,523) versus 3650 (507-20,782) ng/mg protein). Statistical analysis showed that tumour hyaluronan levels correlated significantly with patient's sex and the presence of lymphatic invasion. In addition, high tumour hyaluronan levels were significantly associated with shorter overall survival period (p<0.05). CONCLUSIONS Our results suggest that high tumoral cytosolic hyaluronan levels are associated with lesions of unfavorable outcome in gastric cancer patients. Thus, hyaluronan may provide additional prognostic information to that given by other biochemical markers currently used in gastric cancer.

Abstract
This paper reports on the prevalence and behaviour of Bacillus cereus in gnocchi, a REPFED of Italian origin. A survey of gnocchi under varying storage conditions, revealed that, although B. cereus was found in 33% of the samples, the contamination level was lower than 10(2) CFU/g for the unstored and the refrigerated (8 degrees C) samples. Counts increased with increasing storage temperatures and prolonged storage times in samples prepared without sorbic acid. The effect of different formulations (sorbic, citric and lactic acid) and storage conditions (8, 12 and 20 degrees C) have been evaluated in a challenge testing with spores of B. cereus. Results indicate that the use of sorbic acid in association with citric or lactic acid to pH 5.0 is effective in inhibiting growth of B. cereus and the anticipated shelf life of the product is safe even if temperature abuse occurs. If sorbic acid is omitted, lactic acid can inhibit B. cereus growth during storage at 8 degrees C. On the contrary, when temperature abuse occurs (12 and 20 degrees C), lactic or citric acid are not able to prevent growth of B. cereus.

Abstract
PURPOSE The purpose of this study was to evaluate the role of three-dimensional spiral computed tomographic angiography (SCTA) for the assessment of the feasibility and results of endoluminal repair of infrarenal abdominal aortic aneurysm. METHODS Laboratory studies: Phantom glass aneurysms, filled with contrast, underwent SCTA. The correlation between SCTA and laboratory measurements of linear dimensions and volumes was highly accurate (r(2) = 1.0). CLINICAL STUDIES From the first 7 patients that were suitable for endoluminal repair, the correlation between SCTA and angiocatheter measurements was 0.85 to 0.99 (P <.04), but there was poor agreement between individual values. As determined from the measurements by 2 experienced investigators, intraobserver and interobserver errors for volume calculation in 12 randomly chosen scans from a total of 120 scans were 5.7 and 4.4 mL, respectively (range of volumes, 100-403 mL). The conditions of 53 patients were judged suitable for endoluminal repair of which 30 patients reached 1 year or more follow-up. The median aneurysm neck length and diameter were 24.5 mm (range, 11.5-60.8 mm) and 23.4 mm (18.3-31.5 mm), respectively. The fate of the sac after endografting by two techniques (pre-expanded polytetrafluoroethylene [PTFE] fixed with Palmaz stents and endografts) was defined with three-dimensional SCTA. RESULTS The sac volume after endografting by pre-expanded PTFE (n = 12 patients) showed a significant median increase (P =.02) from 129 mL before surgery to 141 mL at 5 days after the operation with no change at 6 (139 mL), 12 (137 mL), and 18 (159 mL) months later. With the endografts (n = 18), there was an initial increase in median volume at 5 days (179-194 mL; P =.02) and then a significant shrinkage at 6 (148 mL; P =.012) and 12 (94.9 mL; P =.02) months. CONCLUSION Three-dimensional SCTA has been validated and is both precise and reliable. Interobserver and intraobserver errors are within acceptable ranges. Angiocatheter measurements are less accurate and may give misleading information when used for patient selection and endograft construction. The sac volume increased after endografting and later shrank in patients who were treated with endografts, but not in those patients treated with pre-expanded PTFE. We propose that three-dimensional SCTA should be regarded as the gold standard for linear and volumetric measurement for infrarenal abdominal aortic aneurysm.

Abstract
In this paper different models of anosognosia are confronted and data concerning denial behaviors are presented that were collected on a selected population of right brain-damaged patients affected by motor and neglect disorders. Anosognosia for motor impairment and anosognosia for cognitive impairments were found to be dissociated, as well as anosognosia for the upper and lower limb motor impairments. These findings are then discussed in an attempt to choose the more suitable theoretical framework for interpreting the various disorders related to denial of illness.

Abstract
We examined 25 patients affected from Cooley's disease and five by beta-thalassemia intermedia. The mean age was 15 +/- 6.3 years. Fifteen patients, (18 years or older) three of them affected by beta-thalassemia intermedia, presented ocular abnormalities. So it was impossible to establish a correlation between laboratory data and ocular damages; their observation, with reference to untreated beta-thalassemia subjects, suggested that ocular abnormalities cannot be only attributed to desferrioxamine treatment.

Abstract
We tried to counteract the appearance of galactosemic cataracts in weaned rats by high doses of vitamin E. Rats were fed a diet containing 33% galactose. Cataract development was monitored by biomicroscopy and by several biochemical parameters: K+/Na+ ratio, aldose reductase activity, level of protein and non-protein sulfhydryl (SH) groups. Vitamin E was given parenterally at a dose of 100 mg/kg/day. The K+/Na+ ratio drops after 15 days of galactosemia, while the level of the aldose reductase rises after only 5 days of treatment. The non-protein SH groups lens contents fall from the 5th day of treatment onwards, while protein SH groups are not affected. In short-term experiments vitamin E does not prevent biochemical changes caused by galactosemia. The oxidative insult does not seem to be primarily involved in galactose cataract.

Abstract
ABSTRACTA 50-utterance corpus for each of sixteen mothers during caretaking situations (diapering, dressing, bathing) was extracted from in-home tape recordings obtained over a three-day period. The children ranged from 1; 3.15 to 1; 7 and were classified according to Nelson's referential-expressive distinction. A coding scheme consisting of three categories – communicative intent, focus of attention and evaluation – was employed to characterize the mothers' speech. Mothers of referential children produced a greater number of utterances per caretaking incident, more description and less prescriptives than did mothers of expressive children. The findings suggest that Nelson's referential-expressive distinction in child's speech is related to differences in mothers' pragmatic speech characteristics.

Abstract
Three hundred and seventeen oral glucose tolerance curves have been analyzed by a mathematical model (Ackerman's model).
By application of the model to continuous venous infusion the validity of the Ackerman's hypothesis on the glucose intestinal absorption has been confirmed. The results demonstrated that the intestinal absorption rate of glucose was not statistically changed in diabetes mellitus, but decreased with age.
The period of curve T, which characterizes the glucose-insulin feed-back, the glucose fasting level and the coefficient α, which characterizes insulin removal rate independent of blood glucose and the decrease of blood glucose independent of insulin, resulted in significant differences between normal and diabetic subjects. The error involved in this method was about 7.5 per cent.
